We come to the final installment of my look into what the hell we were doing for the last 27 sessions.
The final two modules of the adventure path mostly take place in the subterranean city of Ilmurea, built by the serpentfolk millennia ago in the caverns of the Darklands. Saventh-Yhi was eventually built above Ilmurea, first as a staging point for an assault upon the serpentfolk and then as a monument to the heroine Saavith, who first defeated the serpent god Ydersius.
In the fifth part, the party has just reclaimed the crystals that allow them to activate the portal to enter Ilmurea in order to find and rescue the Pathfinder Eando Kline who can tell them about the serpentfolk’s plans to resurrect Ydersius. The city of Ilmurea is an interesting place. There are a number of power groups in there. The first the party will likely stumble upon are the morlocks, who are chaotic evil but revere Eando Kline as a god, because the Pathfinder Society doesn’t come equipped with the Prime Directive. With the help of Juliver or any Pathfinders of their own, the party can leverage this to get the little bastards on their side.
Then there are the urdefhan. They’re also evil, a species of Darklands-dwellers related to daemons. They also sort of occupy a similar niche as the githyanki do in brand-name D&D and wield very strange swords with two-pronged blades, like a humongous fork. They’re scheming bastards who want the party to take out a defector who’s lairing with the serpentfolk. This is a way to get them on your side.
There are also some drow hanging about and a neothelid that the party can run into if they’re too nosy. Mine was. Curiosity killed the half-elf oracle, who was replaced by an elf fighter disguised as a half-orc.
Finally, the main event of the adventure is a serpentfolk stronghold where Eando Kline is held captive. It is a good dungeon – presents a variety of foes while remaining logical, interacts with itself and reacts to the player characters if they figure out they’re under assault. Importantly, it’s also manageable in size and length. There are also a bunch of very challenging enemies whose tactics are effective, make sense, and take all sorts of contingencies into account. The BBEG of the adventure ended up being a torturer in the deep dungeons whom the party could not take out and opted instead to flee. First time for everything.
So yeah, I like The Thousand Fangs Below. It’s not perfect, since I think it’s sort of a middle part where the entire plot is about the party doing something in order to be able to do something else instead of doing it because it must be done. To put it in terms of philosophy, their primary goal has a primarily instrumental value instead of an intrinsic value, which I think is also one of the problems in Vaults of Madness. Same goes for Sins of the Saviours in Rise of the Runelords, really. While such an adventure can be fun, I’d prefer each part of an adventure path to be more meaningful than that.
Your mileage may vary, of course. If your players are familiar with the Eando Kline stories from the first three adventure paths, they may be keen indeed on rescuing him, but for my players (and me) he was just some guy out there. Personally, I remember having read them but cannot for the life of me remember what happened. At least he’s not as annoying as Drizzt was.
It may actually be fruitful to think of The Thousand Fangs Below and Sanctum of the Serpent God as the two halves of the same adventure. They blend together pretty well, seeing as all the really interesting stuff you get to do in The Thousand Fangs Below actually has its payback in Sanctum of the Serpent God. Befriended the morlocks? Good, you now have underground infantry for your army. Get along well with the urdefhans? You’ll have their sword. It’s time to march against some serpentfolk.
In Sanctum of the Serpent God, the party finally has enough information to know what to do and the allies to make it happen. Out of the different factions and tribes still left in Saventh-Yhi and the different power groups that are not directly hostile to them down in Ilmurea, they shall build an army, and drop the spears of Saventh-Yhi through the very bedrock of Mwangi itself, deep into the Darklands, to penetrate Ilmurea’s ceiling and give their troops a way to invade en masse. While the army draws out most of the serpentfolk from their main fortress, the party does the commando thing, goes in through a side door and takes out the officer corps, the high priest, and the god.
Well, it’s not quite that straightforward. There’s first a dungeon crawl where they take out a bunch of urdefhans and daemons to rescue a cyclops general who has spent the last ten millennia in stasis, because he’s the only one who knows what the damn spears are for. There’s also a series of assassination attempts on the party that I ended up skipping since I was rather tired of it all at this point and with the stable of one-trick ponies I had, half to three quarters of the party would have died.
The final dungeon is not quite as nifty as in The Thousand Fangs Below, but the endboss, avatar of Ydersius himself, makes up for it. He’s a legitimately tough solo adversary. Usually, a single enemy in Pathfinder RPG gets screwed over by action economy. Four heroes against one enemy means four times more actions directed against the bad guy than the bad guy can wield against the heroes. Simple math. Karzoug the Claimer, back in the 3.5 version of Rise of the Runelords, was victim to this and went down quickly. However, Ydersius is tough. He can withstand a lot of punishment, is immune to a whole lot of interesting tricks and has ways of removing heroes from the field for a few rounds at a time. The final combat was challenging and tense. At the end, the heroes triumphed and cut off the serpent god’s head, but it was close.
Would I recommend the Serpent’s Skull adventure path? No. Not as the whole it is now, and not as written. Adventures two through four have a number of issues and little to make up for their flaws, The Thousand Fangs Below is uninteresting plot-wise, and at the end the whole campaign just feels like it is overstaying its welcome. Much like some its adventures feel more like ways to pass the time until the PCs are high-enough level to take on the next big adversary, the whole campaign feels like it mainly exists to be a traditional campaign between the nation-building sandbox of Kingmaker and the horror extravaganza that is Carrion Crown.
It is not, I must hasten to add, a total loss. Souls for Smuggler’s Shiv is one of the best published adventures I’ve ever seen. The campaign itself, with some heavy rewriting, can be made into a pretty great work. The potential is all there, it’s just the execution that’s wanting. Add a local Mwangi faction, perhaps as a replacement for the Free Captains (the devil are they doing inland, anyway?), squeeze The City of Seven Spears and Vaults of Madness together, add some heavier foreshadowing of Sanctum of the Serpent God into The Thousand Fangs Below to make it feel less like a keycard hunt, and you’re golden.
Of course, the amount of work involved in all that probably defeats the purpose of using a pre-written adventure path in the first place, but it is my hope that after reading this and the preceding installments, you should be equipped to decide on your own whether it’s worth it for you.
